To all whom it may concern:

Be it known that I, J osEPHy F. LAMB, a citizen ofthe United States,residing at New Britain, county of Hartford, State of Cone* necticut,ha-ve invented a certain new and useful Improvementv in MetallicFrames,lof

which the following-is a full', clear,'and exact description.

.My invention relates to metallic frames and has for its object toprovide a metallic frame comprising angle iron portions so' shaped andsecured that the division line in the upper surface shall be at rightangles to the axis of one of the angle Airons and parallelto the axis ofthe other, as distinguished from bein at an angle to the axes vof boththe angle irons. It further has for its object to produce an angle ironframe, one member having a rounded surface to which the straightportions of the outer edges o-f both angle irons are tangential.' Itfurther has for its objectV to produce a frame which is simple and easyto manufacture in addition to having the features referred to.

'- Heretofore, angle'irons have been made in which the Vadjacent endswere similar, resulting in a division line which was at an angle to theaxes of both irons. This construction is .quite difficult to manufactureon account of necessary mitering, and, furthermore, the angular divisionline results in the formation of projections to catch on cloth-- ing andthe like, or upon the hands of the;

user, and injure the same. These difiiculties are avoided in myconstruction.

The following isa description of an emi bodiment of my invention,referencebeing drawin s, 1 is an angle ir'onlhaviiig a horihad to theaccompanying drawings, in which,

Fig. lis a side elevation of a frame em bodying my invention;

Fig. 2. is a plan view of the same; Fig. 3 shows a side elevation of oneangle iron in reverse position; while, Fig. 4 shows a plan view ,of thesame. Referring more particularly toV the.

zontal ange 2 and a vertical flanoe 3, the same being cut off at 4 in aplane at right angles tofits axis. 5 is a second angle iron having ahorizontal flange 6 and a vertical flange Y7. The ends ofthe horizontalflange 6 are preferably rounded as at 8 and the vertical flange is cutaway at 9 9, leaving extensions 10-10 on the horizontal flange,

whose'lengths areiequal to lower surface of the flangeQ. rlhe angleiron1 is then placed with its end abutting the angleiron 5,. as shown inFigzfQ, so that the A vertical end of the flange 3 abuts the, verticalsurface of the flange 7 and the Vin-. ner surface ofthe flange 3 isplane as theend of the flange 7 The two `horizontal portions 2 and 6vliev in the same horizontal plane, theextension 10 on the' the coactingend of the flangef2. The rounded surface is `such that the Vouter edgesof Y i l part 6 having its edge abutting the portions 2' and 6v aretangential thereto.

as shown in F ig. 1. The upright ends of the i portion 14 are severed ona horizontal plane and'bear against the, lower edgesof thev flangesand.'i In the manufacture,'the fact that all outso 'i vting is at right,angles so as to require nov Y mitering, simplifiesthe operations andtools required.

The Aframe constructed as described embodies'the improvements andpossesses the advantages above'referred to.` Y

As will be evident to those skilled in the art, my invention permits ofvarious modifi-v cations ywithout departing .fromY the spirit What Iclaim is:

9o Y the appended vcla ims. l

1. In a metallic frame, twoangle irons having horizontal and verticalportions, the

portions of one Vangle iron terminating in the saine plane transversetojits axis, and

the horizontal portion of the other extend'- ing beyond itsverticalportion and having its edge abuttingtheendv of thek horizontal portionof the first iron, and an angular member secured to said angle irons forholding the ends of tlievertiCal portions of the two irons closelyadjacent and in angular relation to one another and the horizontalportion of each angle iron in the same plane as .the horizontal portionof the other.

` 2. In a metallic frame,'two angle irons having 'horizontal andvertical portions,v the portions of oneangle iron terminating in thesame plane transverse toits axis, and

the horizontal portion of the other extending beyond its verticalportion and having `portions of the two irons closely adjacent and inangular relationto one another and the horizontal portion of each angleiron in the sanie plane as the horizontal portion ot thel other.

3. In a metallic frame, the combination Yof an iron having two portionsat rightl angles to one another and both terminating inthe same planetransverse to its axis, one of said portions being horizoiitah a secondiron having two portions, one vertical and the other horizontal, thevertical part of: the second iron terminating in ay transverse plane andthe horizontal part extending beyond said plane, the ends of the twoportions of said rst iron abutting parts of the second iron so that theend of the horizontalportion of said first iron is adjacent to they edgeof said'eiztending portion ot the second iron, and the endy of thevertical portionof; the second iron is adjacent ito' the'eiid ofthevertical portion ofsaid first' iroii,`and means for holding said twoirons togetlier,A said eX tending portion having a rounded ysurfacelsuch that the outer edges of the horizontal portions are tangentialthereto.
